Personal history of vulvar dysplasia

This code indicates a patient's past medical history of abnormal cell growth on the vulva, which is a precancerous condition. While the dysplasia itself is no longer present or active, its prior occurrence is significant for ongoing surveillance and risk assessment.

Assign this code when a patient has a documented history of vulvar dysplasia (e.g., VIN I, VIN II, VIN III) that has been treated or is currently in remission. It is used to signify the increased risk for recurrence or development of vulvar cancer, even in the absence of current disease.

• Do not use this code for active vulvar dysplasia; instead, refer to codes in the N90 category.
• This code is typically a secondary diagnosis, supporting the medical necessity for follow-up care, screenings, or specific treatments.
• Ensure documentation clearly states "history of" or "personal history of" vulvar dysplasia to support code assignment.
